After Mariners first baseman Adam Lind smacked a grand slam at Safeco Field, Beatrix flipped out in a sheer meltdown of grimacing, smiling, bug-eyed joy. She vibrated like a tuning fork, sending her father and mother, as well as those around them, into fits of laughter.

Then the fan cam captured Beatrix’s sugar-and-fan-love overload and Mariners administrators made a GIF of her image and posted it on the team’s Facebook page.
